It seems former talk show host Rosie O’Donnell has joined the ranks of green celebs like Alec Baldwin and Leonardo DiCaprio, reportedly purchasing a 4-bedroom, 3-bath duplex in the 42-unit adaptive reuse building that was once St. Vincent’s Hospital in New York City. The luxurious, $8 million pad located at 130 W. 12th Street is equipped with filtered air and water systems, a customized wireless network, a green roof and a private terrace. Renovated by Cook + Fox Architects, the pre-war building is aiming to receive Leed-NC Silver certification from the US Green Building Council.
